Measuring 518 × 276 × 242 mm and with the positive terminal on the left, it is the direct replacement for lorries that leave the factory with a 225 Ah battery in this format. - Reinforced grids and casing for the severe demands of haulage. - Reliability through repeated starts and when powering cab equipment. - High cranking current for large-capacity diesel engines. - Tolerance of the vibration of thousands of kilometres on the road. ### Vehicles compatible with the Varta N9 battery The Varta N9 is compatible with more than 462 vehicles: it is fitted as standard or as a replacement by brands such as Volvo, Scania, Iveco, Mercedes-Benz, DAF and MAN. For anyone who needs to change the **battery in their Volvo** or Scania, this Varta N9 reproduces the original specifications. It also appears as a replacement in vehicles from BMC, Fap, Renault, Leyland, Ginaf, Dennis, Steyr and Tatra, among other manufacturers. ### Size and fitting of the Varta N9 In terms of format, the Varta N9 measures 518 × 276 × 242 mm (length × width × height) and weighs 62 kg. The positive terminal on the left determines which side the cables run to: it is the detail that causes the most buying mistakes, so it is worth checking before ordering. It uses a B00 hold-down and a type 1 terminal, the system that anchors it to the vehicle's battery tray. For the swap to be direct, the space your current battery occupies must respect those three dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will have to change. ### The Varta N9 and the ProMotive SLI range The **ProMotive SLI** is Varta's starter battery range for commercial and industrial vehicles; it consolidates the former ProMotive HD and SHD names into a single series organised by technology. It delivers a high cold cranking current and a construction designed for the severe demands of heavy haulage. It is the dependable replacement for lorries, buses, tractor units and machinery working long shifts: resistance to road vibration, tolerance of cycling and guaranteed starting even after weeks standing idle. Compared with a passenger-car battery, this range is calibrated for severe, continuous use: greater mechanical strength and more tolerance of cycling and of the knocks of the road. It is the correct replacement for a lorry, bus or machine putting in long days. *This battery used to belong to Varta's **ProMotive HD** or **ProMotive SHD** range; following the brand's commercial renaming (2025), it forms part of the new **ProMotive SLI** series.* ### Why choose a Varta battery Varta is a byword for reliability: original equipment in numerous European vehicles and one of the most proven brands on the market. Replacing your battery with a Varta restores OEM quality — the same performance as the factory-fitted unit — with the manufacturer's backing. Behind Varta is Clarios, one of the largest manufacturers of starter batteries in the world and a supplier to the assembly lines of numerous car brands. That German engineering heritage translates into reliable starting year after year. Varta's production combines automated lines with verification of more than 100 parameters per unit; that traceability is what underpins its reputation for reliable starting throughout the battery's life. ### Manufacturer's warranty The Varta N9 battery comes with the **official manufacturer warranty**. One important warning for industrial vehicles: most lorries carry **two batteries wired in series** (a 24 V installation). If you replace only one, the new battery ends up working alongside the old one — which has already lost capacity and has higher internal resistance; that imbalance leaves one overcharged and the other short, shortens the life of the new unit, and the manufacturer may treat it as misuse and **void the warranty**. That is why it is always advisable to change **both batteries at the same time**. ### Care and maintenance In professional use, checking the state of charge and the battery hold-down regularly prevents breakdowns on the road. Vibration and the high temperatures of the engine bay are the factors that shorten its life the most, so secure mounting is key. Keeping the terminals clean and tight and checking the charging system extends battery life in vehicles that clock up long hours. A well-maintained battery reduces the risk of downtime caused by a no-start. ### Technical sheet Download the official technical sheet for this battery with all the manufacturer data.

In most trucks it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on this page. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On trucks with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile. ### How long does the Varta N9 battery last? Expected lifespan of the Varta N9 is 4 to 6 years in regular truck use without Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured. ### What are the measurements of the N9 model? Dimensions (length × width × height) are 518×276×242 mm — also written as 518x276x242 mm — following the European DIN standard. Always measure the space in your truck before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals. ### Will the Varta N9 battery fit my truck? Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The N9 fits 355 verified vehicle versions in our database. ### Which batteries are equivalent to the Varta N9? Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop trucks. See the "Equivalents" section to view recommended options at the same performance level. ## Compatible vehicles This battery fits 355 vehicles.
